* Objective of the additional terms (license)
* 1) Is to extend the software freedom to freedom to work.
* 2) To ensure that knowledge is free from monopoly of agencies.
* 3) To avoid a situation where big corporate or investor can buy out free software groups and companies and then start milking the communities built around it.
* (this trend can be seen how the freedom is curtailed in companies that get Venture Capital funding.)
